I am not entirely sold. The 51% thing is the preponderance of the evidence standard, which is the usual burden of proof for civil proceedings (where no one is going to jail). It seems to me that if it is more likely than not that the accused did sexually assault the victim that some action should be taken - for example, the alleged attacker needs to move to another campus for a year so the victim can graduate without seeing him every day. Again, no one is going to jail, no one is convicted of anything or has a record, it isn’t even public, because of privacy rules.
The alternative is that *nothing* happens, even though the preponderance of the evidence favors the victim.
